To all whom tn-tay con/cernb #A Beit known that I, M CGLERHJPARKEE, a citizen vof the `United States; residing' at Los Angeles, in the' county of Los Angeles and State of California, have Iinvented a newland useful Router-Plane, of which thev following is a specification'. i 'f l This inventiomrelate s to improvements in router-planes, and Vparticularlytol the adjusting and clamping of the cutting knife or bit. The router-plane' formingthefpresent in'- vention vis particularly adapted for routing out seats for door butts or hinges andfor cutting lout for locks and strike-plates for the'sam'e.

-The vplane is of 'value in cutting'seatfsfor'other building hardw'are or material Ethat requires inlayng; x j, AK n i. .i ,I

. 'The accompanyingdrawings illustrate the invention, andreferringitothe same', "Figure I is a side view of the router-plane with-'part of the stockbroken away, showing the preferred construction Fig; II is a: side viewof the router-plane, with part of the'stock broken aw-ay, of another form. Fig. III is af bottom view of the form shown inFig. I. Fig. IV

is aviewlooking toward-the nose of the form shown in Fig.- II.` Fig. Visasection on line V V,.Fig. II. Fig. VI is a detail in perspective.of the cutter o r bit.=` Fig. VII isa detail in perspective of the clamping-rod.

1 designates the stock, which preferably tapers throughout its lengthas shown, being wider at the heel than at the nose; 1

2 designates the cutting iron or bit, which is provided with a squared shank 3, the upper end of which is threaded, as at 4. The squared shank 3 is received by the stock of the plane in a square hole, and when in position the flat faces of the shank engage the fiat faces of the hole to hold the shank from rotation relatively to the stock, the hole extending substantially at right angles to the bottom of the stock, and the cutting-iron 2 projects slightly downward and forward from the rear part of the throat 5 of the stock.

6 is a knurled thumb-nut which is mounted on the threaded shank 3, the stock 1 being slotted to receive the thumb-nut 6, and the edges of the nut protrude, as shown in Fig.

y III, so as Ito be lreadily `grasped' by the fingers inladjusting the cutting-iron.

7 is a clamping-bar having an eye' 8, which is squared internally to receive the shank 3 of the cutting-iromthe shank 3 loosely fitting in the eye. The other'end of the'clamping-bar 7 is threaded, as at 9, and carriesja locking'- nut 1'0, the periphery of which is provided with square notches 11,-which afford shoulders against which a tool may be struck-such, for instance, as a nail --setto tighten the clamping-nut securely.- a Y The stock li'sslottedto receive'the clamping-nutlO, and a washer 12`is provided within the stock 1, against which lthe locking-nut bears when screwed'tight.'A t

As shown, the clamping-bar extends from the rear of the throat 5 nearly to the Aheel of the plane'and is inclined so as'v to bring the clamping-nut well above the bearing-face or bottomy ofthe stock.

` In the: preferred form the" stock 1 is made of av single piece of wood, and in order to put the clamping-bar in place in the stock the vstock is-drilled from the heel toward the throat with a hole of sufficient diameter to allow of the passagethrough itA of lthe eye 8; and a wooden sleeve 13, which is drilled centrally to receive the locking-bar 7, together with the lockingbar 7,' is slipped into the hole in the stock from the heel, the sleeve before being inserted having had glue applied to its surface and the hole in the stock also having had glue'applied to its surface, so that when the sleeve is in place in the stock the glue sets and the sleeve becomes practically part of the stock. A plug .14 is then glued into the stock to fill the end of the hole. Another form is shown in Fig. II, in which the lower part of the nose 15 is fastened to the upper part 16 by a tongue-andgroove joint, a tightening-screw 17 passing down through a wide slot 18 in the stock and screwing into the adjustable part 15. When the h ole in the stock in such cases being drilled of a size to just receive the shank of the locking-bar. After the locking-bar is in place the nose 15 may be fastened by tightening the screw 17.

When the lock-nut 10 is screwed up tight, it draws the locking-bar 7 to the rear and forces the shank 3 tightly against its squared seat in the stock 1, and the cutting-iron 2 is thus prevented from turning sidewise or from slipping up or down. To adjust the cutting-iron 2, the lock-nut 10 is loosened, which frees the 'shank 3, so that the nut 6 may be readily turned by the fingers to raise or lower the cutting-iron 2, and when it has beeny brought to the desired position the lock-nut 10 is again tightened, being easily forced very tightly into place by inserting a nail-set in a notch of the lock-nut and tapping the same. v

I havefound in practice that a plane constructed as herein set forth more than doubles the capacity of `a.frnechanie in hinging doors and in vdoingother similar work and that the grade lof Work isl also improved to a marked degree.

What I claim is- 1. Astock having a throat and having ahole extending substantially at right angles toV the bottom vof the stock, a cutting-iron having a shank lying in said hole, the shank and the part of the stock engaging therewith being formed with engaging parts to hold the shank from rotation, the shank. having a threaded portion and a nunon the threaded portion for adjusting the cutting-iron, and means for clamping the shank. A y

2. Astock havingathroat, andhavinga hole with a fiat face extending at substantiallyright anglesto the bottomof the stock, a cuttingironfhaving ashank with a fiat face lying in the hole, the shank having a threaded portion, anda nut on the threaded portion for adjusting the cutting-iron, and means for clamping the shank. i v

3. A stock having a throat, and'having a hole with a fiat face extending substantially at right angles to the bottom of the stock, a cuttingiron having a shank with a flat faceulying in the hole, the shank having a threaded portion,

a nut on the threaded portion for adjusting the cutting-iron, means. for clamping theshank, and a clamping-bar having an eye through which the shank passes, the clamping-bar havinga threaded portion, and a nut on the threaded portion for tightening the clamping-bar.

4. A stock, a cutting-iron having a squared shank threaded at one end, the shank lying within a square hole in the stock and substantially perpendicular to the bottom of the stock, a nut on the threaded portion of the shank within a slot in the stock, a clamping-bar having a squared eyewhich receives the shank of the cutting-iron, the clamping-bar having a threaded portion, and a nut on the threaded portion in a slot in the stock.

5. A stock, a cutting-iron having a squared shank threaded at one end, the Vshank lying within a square hole in the stock and substantially perpendicular to the bottom of the stock, a nut on the threaded portion of the shank Within a slot in the stock, a clamping-bar having a squared eye which receives the Yshank of the 'cutting-iron, the clamping-bar having a threaded portion, and a nut on the threaded portion ina slot in the stock, said latter nut having a notched periphery. f

6. A stock, a cutting-iron having a squared shank threaded at one end, the shank lying within .a square hole in the stock and substantially perpendicular to the bottom of the stock,

,a nut on the threaded portion of the shank i a MCCLUER H. PARKER.
